After a receiving antenna (A) is inserted from a slot (B) into a housing portion (B) formed between cover members (B, B), the slot (B) is pasted so as to secure the receiving antenna (A). The receiving antenna (A) is thus housed. Further, a tab (B) which extends from one side of a pasted edge portion, holes (B, B) that penetrate opposing surfaces of the cover members (B, B), and perforated lines (B, B) running from the slot (B) to the holes (B, B), respectively, are provided. Therefore, the receiving antenna (A) can be easily attached to the antenna cover (B) and to an outer surface of a subject (), and the receiving antenna (A) can be easily removed from the antenna cover (B) and from the outer surface of the subject ().

Antenna cover and antenna apparatus

A method of performing treatment on a desired part of a cavity includes use of an endoscope having a guide wire, a therapeutic instrument and a therapeutic instrument elevator base capable of guiding the instrument to a desired position. The guide wire is inserted into an insertion channel of the endoscope and located in a desired position in the cavity. The instrument is moved from a position in the cavity to a position closer to the operation portion of the endoscope than to the distal end of the endoscope. While a guide wire fixing means at the distal end of the endoscope fixes the guide wire, the instrument is completely pulled out from the instrument channel of the endoscope.

Method of using a guide wire, therapeutic instrument and endoscope

An adapter for an endoscope of the present invention includes: a locking device for attaching and detaching that attaches and locks this adapter for an endoscope onto a predefined position on an endoscope control part; and a first treatment tool locking device that keeps a treatment tool at a first predefined position. Furthermore, at the first predefined position, a guidewire entry aperture of the treatment tool and an entry aperture of a forceps plug are separated in such a way as to face each other along substantially the same line.

Adapter for endoscope and endoscope

Guide wire fixing means is provided for an insertion portion of an endoscope, and a guide wire is releasably engaged when inserting/removing a therapeutic instrument running on the guide wire with a distal end portion of the guide wire inserted into a therapeutic instrument insertion channel of the endoscope being led out from a distal end opening portion of the channel.

Endoscope and endoscope system thereof

This endoscope apparatus adapted to meter NMR (nuclear magnetic resonance) is provided with an endoscope having a channel and an NMR metering probe insertable through the channel. The endoscope has an elongate insertable part having an observing window and illuminating window in the tip part, an observing system for observing an object to be imaged by receiving a light from the object entering through the observing window, an illuminating light output system emitting an illuminating light through the illuminating window and a hollow channel formed within the insertable part and opening in the tip part. Preferably, at least the tip side of the insertable part if formed of a non-ferromagnetic characteristic material. The NMR metering probe has a signal transmitting member insertable through the channel of the endoscope, connected at one end to the NMR metering apparatus and able to transmit high frequency signals and a loop-like antenna part connected to the other end of the signal transmitting member and projected out of the opening of the channel.

Endoscope apparatus

This NMR metering endoscope apparatus is provided with an endoscope body and an NMR metering loop-like antenna. The endoscope body is provided with an elongate insertable part having an observing window and illuminating window in the tip part an observing system for observing an object by receiving a light coming from the object and entering through the observing window and an illuminating light outputting system emitting an illuminating light out of the illuminating window. The NMR metering antenna is fitted to the outer periphery including the tip surface of the insertable part of the endoscope body and can be connected to the NMR metering apparatus.

An endoscope according to the present invention comprises an observation optical system and an insertion section which includes a bending tube. A plurality of segments, which are rockably connected to one another, are arranged in the bending tube, and wire guides are fixed to the inner peripheral surface of each segment. One end of each of bending-control wires is fixed to the segment at the distal end portion of the bending tube. The other end of each wire extends to the proximal end portion of the insertion section, through the wire guides of the other segments. In this arrangement, the bending tube is bent by pulling the other ends of the bending-control wires. The endoscope further includes bending means arranged in the bending tube and adapted to bend, when the bending-control wire is pulled, the bending tube for moving the observation optical system such that the center of the system moves from the center of the insertion section to the periphery thereof. Thus, even though the bending tube is bent sharply, the position of a flexible tube of the insertion section, which may possibly obstruct the field of view, can be shifted to the right or left from the center of the field, thereby keeping the view field entire.

Endoscope

An endoscope has a flexible insertion section extending from an operation section. A chamber is formed in the extended end of the insertion section to open externally, and a guide channel extends from the chamber to an inlet formed at the operation section through the insertion section. A guide member is movably arranged in the chamber. One end of a wire is coupled to the guide member, and the member is rotated by pushing or pulling the wire. When a treating unit is introduced into the chamber through the inlet and the guide channel, the guide member guides the end portion of the treating unit in a predetermined direction. The chamber has a side wall for guiding the member, and the member has a side wall opposite to the side wall. A friction reducing member is fixed to the side wall and contact with the side wall of the chamber so as to reduce the friction between the side walls.
